METHOD FUR WRITING OF? PRINTING WlTH METALLIC} LEAF.

To all whom it may concern.-

Be it known that I, FRANK S. HALL, a citizen of the United States; residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Methods for Writing or Printing with Me tallie Leaf, of which the following a speciiication.

My invention has relation to methods for writing, printing, or designing letters, characters, &c., upon suitable objects with metallic leaf; and theobject thereof is to pro-- duce a method whereby metal leaf may be so superposed on an object that its permanency is assured.

It is well known in the art to which the in vention appertains that metal leaf, such as goldleaf, is marketed in sheets or leaves of metal of the proper thickness alternately placed betweenjthe pages of a gold-book. In using metal in this form the leaves are successively lifted from betiveenv the pages by means ofa; brush or other suitable tool which hasbeenpreviously slightly greased by rub 5 bing overtthehair ion; the; head of the user. especiallyizin the case of gold, re i areeasily blown away geable by the slightest Hence their use red the loss attendant y W ling gold is consider- M tal leaf, Qaiid especially gold -leaf,

is usedtextensively. by bookbinders for the printing of names on bound volumes,card cases, and other objects. The customary manner in which gold-leaf is applied by bookbindersconsists in firstplacing the book or whatever object is to be printed in a press and then forming on the same with type an impression of the letters which are subsequently to be covered with goldleaf. The book is then withdrawn and a proper sizing placedover the spot where the printing will Thesheet of gold-leaf is then laid over the place where the type will press and the book replaced in the press and the type forced onto the=golcl-leaf,..which drives it into the outlines formerly produced by the type, and after a" suitable length of time has elapsed the type iswithdrawn and the surplus gold not pressed in by the type wiped away. Excepting in well-equipped binderies it is necessarytojrepeat this process for each line of type which is used, and the process be ing exceedin ly slow is therefore relatively expensive. (Irold-leaf can only be appliedto Specification of Letters Patent.

such articles as books by means of type which press firmly downward in one place, and in each instance type or a proper male die must be employed'to shape the letter or design which is to be placed on the book in gold-leaf. Heretofore it has been impossible to place gold-leaf upon articles in a manner equivalent to the placing of ink on paper by the pen of a writer on account of the fact that the passing of any tool over the gold-leaf itself would at once tear it and move it from posi tion, and if it were possible to so apply goldleaf in this manner the gold would not adhere to the article on which it was placed sufficiently firmly to be a permanent part thereof, and hence the object of this invention is to produce a method whereby a sheet or leaf of metal may be properly mounted on a suitable backing and portions thereof may be rapidly and easily transferred to any other object upon which it may be permanently placed and from which the metal can? not ordinarily be removed.

In mounting metallic leaf opportunity is given to the bookbinder to place on books and similar articles facsimile copies of signatures, &c., in gold-leaf in less time and with .in the accom anying drawing, as it is to be understood t at changes, variations, and modifications can be resorted to WlllCll come within the scrope of the claims hereunto appended.

The drawing presented is a .perspective view of the mechanical instrumentalities in use, which I prefer to employ in my improved method.

It will be here stated that the description will be confined to the placing of gold-leaf on articles, for the reason that it is the customary and best metal employed in this art to illustrate the adaptability of my improved method, although other metals of suitable malleability may be employed.

In the drawing, 1 represents a hollow needle carried by the hand of an operator, to

which is connected a rubber tubing 2 attached pressure to an ordinary gas-jet 3, so that a constant supply of fluid fuel may be supplied to the needle without interruption. This needle 1 is chow and has near its pointed end a pair 0 openings 4, only one of which is shown in t e drawing, and from these openings the fl id fuel constantly escapes. It will be stated that this needle, as described, does not differ materially from the ordinary pyrographic needle in common use for burning wood, excepting that the openings for the escape of the fluid fuel are placed farenough from the point thereof to heat the same sufficiently for 'use in my im roved method, but not near enough to ren er needle red -hot. i In using this needle the very small blue flame is-allowe'd to exist-at the o enings 4. The placing ofthe o e'ning's 4 bac ward from the point also enab es it to be made sufficiently strong to permit considerable pressure to be used when this tool is employed. i I v In carrying out my improved'rnethod lace a sheet of paper, having thereon a coatmg of paraffin-wax or its e uivalent, over a sheet of gold-leafawhile stil in the book in which it is retailed, and by a slight rubbing pressure over the back face of the paraflincoated paper the gold-leaf is caused to adhere thereto with reat tenacity. This sheet pf paper (indicated in the drawing by the refrence-numeral 5) is then laid over any ob- Fect, such as a sheet of leather, (designated in the drawing by the reference-numeral 6,) andthe operator writes or draws on the rear face of the parafiincoated paper with the heated point of the needle 1. This may be done rapidly and with a relatively slight, although firm, pressure, and after the operation of Writing is finished the paraffin-coated paper islifted up and the gold which was displaced by the heat and ressure of the heated needle will be found to be permanently adherent to the leather or other substances on which it is intended to reproduce the writings or designs impressed on the back face of a paraffin-coated paper.

It will be seen from the foregoing description that any artistic design may be laced on an object in metallic leaf without t e necessity of making a metallic die therefor, and

the presence of the waxed paper will keep the the point of'the I of gas is greatly reduced andjonly'a I V with ing t employed-and other means than parafiin may,

point of the needle from the object on which the metallic leaf is to be placed and absolutely prevent the burning thereof.

It will be further seen that a facsimile of a persons signature may be readily placed on a book, card case, or any 0th bject by simply having the person who's g is desired to reproduce write his amepnjthe rear face of the waxed paper, and -'by'f0llow ing the lines on the paper an accurate copy thereof will be made.

The rapidity with whichith'is method can be used for the placin'gof'metallioleaf ui on objects commends it botlijon account 0 its comparative cheapness and l the-universality ofitsuse. 1 ,Whilel have found that paper covered paraffin is the best backing for sustaine metalfleaf, other materials may be be used to the adherence of the metallic leaf 5 I Havin as described my invention, what I sirefto secure by Letters Patent,1 Y; 1. Tha 1 ovement in the art of impres ingmetaflic le'af on articles, which consists inplacing the metallic leaf with a backing adhering thereto upon the article, and

then subjecting 'said backing to heat and pressure from a manually-operated continue ously-heated needle,

whereby said leaf is caused to detach from 'saidjbaokin an here to said article 2. That im rovement far. ofimpressing meta lic leaf on articles, wlii'ch oonsists in placin f the metallic leaf with a backing adherin t ereto upon the article, placing on said bac 'ngia suitable pattern or copy, and then subjecting said backing along the lines of said pattern or copy to heat and pressure from a manually-controlled continuously heated needle, whereby said leaf is caused to detach from said back and adhere to said article.

.In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
